Right ventricular enlargement (also known as right ventricular dilatation (RVD)) can be the result of a number of conditions, including: pulmonary valve stenosis; pulmonary arterial hypertension; atrial septal . Right atrial enlargement (RAE) and right ventricular enlargement (RVE) have been associated with several cardiac conditions. RAE may result from congenital abnormalities of the tricuspid valve and .

Lateral examination of a chest x-ray (CXR) shows the normal in the upper row (a,b) and the abnormal and enlarged in the .Left ventricular (LV) hypertrophy consists in an increased LV wall thickness. LV hypertrophy can be either secondary, in response to pressure or volume overload, or primary, i.e. not .lv enlargement cxr Left atrial dilatation causes straightening of the left heart border. LV enlargement typically leads to an increase in the CTR on radiographs. However, this .
Although a normal CXR does not exclude pulmonary hypertension, an abnormal CXR is commonly seen in confirmed diseases . CXR findings include . Radiographic features. In most cases, merely 'eye-balling' a chest x-ray will be sufficient in detecting cardiomegaly (as the heart is either clearly normal in size or clearly abnormally enlarged). In equivocal .
mild RV enlargement. basal diameter increased (>4.2 cm) left ventricular size still exceeds that of the RV; moderate RV enlargement. the size of the RV approximates that of the left ventricle (LV) the left .

In some areas it has been replaced by more sensitive techniques; for example, sonography in the evaluation of pericardial effusions. Still, the chest .
Cardiac enlargement on CXR (CTR > 55%) guides further in the evaluation of cardiomegaly. In this view, the right cardiac border is formed, cranially to caudally, by the superior caval vein, ascending aorta, right atrial appendage, and the right atrium, while the left cardiac border is formed, cranially to caudally, by the aortic arch, pulmonary trunk, .the posterior border of the heart is divided into thirds; 1/3 for the LA and 2/3 forthe LV. the diaphragmatic border is divided into thirds; 1/3 for the LV and 2/3 for the rest of the diaphragm Ashley Davidoff MD 15416C02Wlateral.8 rule of thirds .

Honeycomb lung, Increased interstitial markings, Mediastinal widening on mobile CXR, Pulmonary fibrosis, Pseudoinfiltrates on CXR, Pulmonary opacities on CXR, ABDO: Gas on abdominal X-ray, Kidney mass, In the lungs LV failure will lead to dilatation of pulmonary vessels, leakage of fluid into the interstitium and the pleural space and finally into the alveoli resulting in pulmonary edema. Right ventricle (RV) . a right ventricle:left ventricle basal diameter ratio exceeding 1.0 (RV/LV ratio >1) a left ventricular eccentricity index >1.1. a manifestation of flattening of the interventricular septum, assessed by dividing the short-axis diameter of the LV parallel and then perpendicular to the septum and dividing these values to yield an eccentricity index
The assessment of the pulmonary hila on chest x-ray is important for detecting potential mediastinal and lung pathology.. Several features of the hilum and hilar point can be assessed:. shape. normally appear as K or C-shapes on either side. contents: pulmonary arteries and veins, bronchi, lymph nodes

The heart will be larger then expected. The radiologist will often make this diagnosis using his experience instead of precise measurements. The enlargement is often graded as mild, moderate and severe. Symptoms of enlarged heart. Some of the causes of an enlarged heart can cause breathlessness such as heart failure. The double-density sign, also known as the double right heart border, is seen on frontal chest radiographs in the presence of left atrial enlargement, and occurs when the right side of the left atrium extends behind the right cardiac shadow, indenting the adjacent lung and forming its own distinct silhouette 1-3..
